WRINGING DEVICE FOR MOPS.

Specification of Letters Patent.

Patented April 23, 1907.

Application filed April 28, 1906- Serial No. 314,247.

To all whom, it may concern.-

Be it known that I, CHARLES LOVELAND KRABER, a citizen of the United States, residing at Quincy, in the county of Adams and tate of Illinois, have invented a new and useful Wringing Device for Mops, of which the following is a specification.

This invention relates to floor mops and relates more particularly to a wringing device adapted to be used as an attachment in connection with floor mops in ordinary use, or to be used as a permanent part of the floor mop with which it may be manufactured.

The objects of the invention are to provide a wringing device of this character which shall be of simple and substantial construction, easily operated, and possessed of other important features which will be more fully set forth in the following description of the arrangement and combination of parts.

In the accompanying drawing, which represents certain embodiments of which the invention is capable, Figure 1 is a perspective view of the mop showing the 'wringer by full lines in its operative position, and by dotted lines in its inoperative position. Fig. 2 is a side elevation of the wringer drawn on an enlarged scale. Fig. 3 is a transverse section of the mop handle at the wringer. Fig. 4 is a perspective view of a modified form.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

Referring to the drawing, a mop is illustrated of common construction, LllC same comprising the handle 1, the head 2, and the mop cloth 3. As far as my invention is concerned, the mop can be of any approved construction. The wring-er comprises a holder or support 4 which in the present illustration takes the form of a band extending around and fitting the handle 1 of the mop. The frame 4 is adapted to move lengthwise along the handle and this movement is guided by. one or more rods, one being shown at 5 in- Fig. 1, and 2 in Fig. 4. The rod 5 engages with the frame in such a manner as to prevent the latter from turning on the handle and the rod preferably extends inside the frame, as shown. At its ends the rod is shaped in any suitable manner for enabling the ends to be fastened to the handle, as, for instance, the ends are formed into angular-1y disposed tapered points 6 which drive into the handle and serve to hold the guide rod thereon.

Extending between the handle and the I guide rod, the latter being suitably separated from the handle, is a shaft 7 that is journaled in the frame 4. At one end of the shaft is arranged an operating handle or crank 8. To the other end of the shaft, the free end of the mop cloth 3 is operaiivelyeonnected. As the shaft 7 extends between the guide rod and handle, the inwardly turned ends of the guide rod serve as stops for limiting the movement of the framed on the handle. This arrangement of the parts also prevents the frame from turning around the handle during the wringing operation.

In order to connect the free end of the mop cloth 3 directly to tilt) shaft, and at the same time enable the cloth to be twisted or wrung, the shaft 7 arranged at an angle to a transverse plane extending through the bandle. In practice, I find that about 45 between the transverse plane and the axis of the shaft is suitable. The cloth is connected to the shaft by means of a loop or hook 9 turned at the end of the shaft. By this arrangement, the rotation of the shaft 7 will cause the mop cloth to be easily twisted or wrung and the relation between the loop 9 and the tion is somewhat similar to the universal joint. Hence, the rotation of the shaft 7 tends to impart rotation to the mop cloth, but since the latter is non-rotatably held at one end to the head 2 of the mop, the cloth is twisted or wrung.

A spring clasp or retainer 10 is provided at the upper end of the frame. This clasp may be pivotally or otherwise secured to the frame much in the same manner as a bail, and it serves as a handle whereby the frame -i can be moved up and down on the mop stick. The clasp 10 preferably takes the form of a stout wire looped and provided with two inwardly bent portions 11 which are adapted to spring over or around the handle and firmly grip the same. Besides assisting to prevent the frame from slipping around on the mop handle, the clasp 10 also firmly holds the frame of the wringer in its raised or lowcred position.

Referring to the modification shown in Fig. 4, two guide rods, which are indicated at 12, are employed. These preferably take the form of a single piece of stout wire or rod which is bent upon itself to form the looped portion 13. The ends of the wire are formed into suitable fastening devices, such as taend of the mop cloth is such that the opcra IIO ' the clasp over the handle.

pered points, for attaching the same to the limiting the movement of the holder, a shaft mop handle. The rod portions 12 may engage the frame 4 in any suitable manner for preventing it from turning on the handle, as, for instance, by extending inside the frame. In the present illustration, the rod portions 12 of the guides are disposed on one side of the mop handle, and the looped portion 13 extends around the latter. The shaft 7 of the wringer extends between the guide rods 12 and the mop handle, so that the frame is retained in place on the handle by the looped portion 13 and the bottom ends of the guide rods, the said looped portion and ends of the guide rods serving as stops for limiting the movement of the wringer frame. Then the wringer frame is in its lower position, or near the mop head, the upper end of the guide rods 12 swing apart, or, in other words, they possess a certain tension. hen the mop frame is raised, the frame causes the guide rods to be drawn together so that the looped portion 13 is caused to firmly grip the mop handle. This tension possessed by the guide rods also serves to frictionally hold the frame in its lowered, or any intermediate position.

When the mop .is used for mopping up a surface, the wringer is moved to the position shown in dotted lines in Fig. 1, so as to permit the mop cloth to hang loose. To move the wringer, the frame 1 is first unlocked by disengaging the clasp 10 from the handle 1. The clasp 10 may serve as a grip by which the user can move the frame to its lower position. After being moved to its lower position, the frame is again locked in place by springing When it is desired to wring out the mop cloth, the wringer frame is moved to the position shown by full lines in Fig. 1, and locked in such position. While onehand of the user grips the clasp 10 and the handle of the mop, the other turns the crank 8, thereby twisting and wringing the mop cloth. After the cloth is wrung, the crank is turned in the opposite direction so as to unwind the cloth and permit it to hang loose when the wringer frame is again lowered to the working position on the floor.

I have described the principle of operation of the invention, together with the apparatus which I now consider to be the best embodiment thereof, but I desire to have it understood that the apparatus shown is merely illustrative and that the invention can be carried out by other means.

Having thus described the invention, what is claimed is 1. The combination of a mop, a head therefor, and a handle, with a wringer for the mop, said wringer comprising a holder movable along the handle of the mop, a guide member for the said holder secured 5 to the handle, its ends serving as stops for-i j ournaled on the holder which moves therewith between the guide member and handle, means for rotating the shaft, and means for connecting the mop with the shaft for wringing the former.

2. The combination of a mop, a head therefor, and a handle, with a wringer for the mop, said wringer comprising a frame extending around the handle and movable thereon, means for guiding the movement of the frame, a resilient member hingedly connected with the frame and arranged to grip the handle at any point within the range of movement of the frame, and a crank-shaft journaled on the frame with its axis inclined at an angle to that of the handle and provided with an eye disposed at one side of the handle for connection with the free end of the mop and with a crank disposed at the opposite side of the handle.

3. The combination of a mop, a head therefor, and a handle, with a wringer for the mop, said wringer comprising a frame movable along the handle'of the mop, means for guiding the movement of the frame, a looped resilient member arranged to grip the handle for locking the frame in adjusted position on the latter, and a crank shaft carried by the frame and connected with the free end of the mop for wringing the same.

4. The combination of a mop, a head therefor, and a handle, with a wringer for the mop, said wringer comprising a frame, a member on the handle for guiding the frame, its ends adapted to serve as stops for holding the frame 011 the handle, a spring clamp pivoted on the frame for locking said frame to the handle, a crank shaft journaled on the frame, a crank on one end of the shaft, and an eye on the opposite end of the crank.

5. The combination of a mop, a head therefor, and a handle, with a wringer for the mop comprising a band mounted for movement longitudinally of the handle, a guide means composed of a double wire for guiding the movement of the band on the handle and for preventing the band from turning, said means having a looped portion extending around the handle and adapted to grip the same, the ends of the wire being fastened to the handle, a shaft journaled on the band with its axis inclined to the line of movement of the latter, means for rotating the shaft, and a loop attached to the shaft for engagement with the free end of the mop.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
